Karyopharm Therapeutics gets FDA OK for Xpovio
Karyopharm Therapeutics has received the Food and Drug Administration’s green light for Xpovio (selinexor) tablets in combination with the corticosteroid dexamethasone for the treatment of adult patients with relapsed refractory multiple myeloma who have received at least four prior therapies and whose disease is resistant to several other forms of treatment, including at least two proteasome inhibitors, at least two immunomodulatory agents, and an anti-CD38 monoclonal antibody.
“While there is no cure for multiple myeloma, there are FDA approved treatments to target the cancer and slow down the spread of the disease. Sadly, often over time, patients can exhaust all available treatments and still see their disease progress,” said Richard Pazdur, director of the FDA’s oncology center of excellence and acting director of the office of hematology and oncology products in the FDA’s Center for Drug Evaluation and Research. “Today we approved a treatment under our accelerated approval program that provides a treatment option for patients with multiple myeloma with no available therapy.”
Multiple myeloma is cancer that begins in plasma cells (white blood cells that produce antibodies) and may also be referred to as plasma cell myeloma. Abnormal plasma cells build up in the bone marrow, forming tumors in many bones of the body. As more antibodies are made, it can cause blood to thicken and keep the bone marrow from making enough healthy blood cells.
